Ventilators serve as life-support devices where stable operation directly relates to patient safety. The WF200DP medical pressure sensor ensures perfect synchronization between equipment and patient breathing patterns through precise airway pressure monitoring and real-time feedback control. This MEMS-based differential pressure sensor has become an indispensable core component in modern ventilator systems due to its high accuracy, rapid response, and long-term stability.
1. Critical Role of MEMS Technology in Ventilators
압력 모니터링의 의학적 중요성
Ventilators create artificial pressure differentials to replace natural respiratory function. During normal breathing, inspiration creates negative pressure through chest expansion, while expiration generates positive pressure through alveolar elastic contraction. The WF200DP sensor precisely replicates this physiological process, ensuring accurate assessment of patient respiratory needs through real-time airway pressure monitoring.
차압 감지 원리
WF200DP employs differential pressure detection technology, simultaneously monitoring pressure differences between two ports. This design enables the sensor to eliminate environmental temperature and atmospheric pressure variations, providing more stable and accurate measurement results. Internal silicon diaphragms undergo minute deformation under pressure, converting mechanical signals to electrical signals through piezoresistive effects.
신호 처리 및 제어 피드백
Sensor-generated analog signals undergo amplification and digital conversion before transmission to the ventilator’s microcontroller unit. The MCU analyzes pressure data to assess patient respiratory status, adjusting motor speeds and valve openings to control airflow supply and discharge, achieving precise synchronization with patient breathing.
2. WF200DP Sensor Technical Advantages
고정밀 측정 기능
WF200DP sensors feature ±0.25% measurement accuracy, detecting extremely minute pressure variations. This precision level proves crucial for ventilator applications, as patient respiratory pressure changes often involve only hundreds of pascals, requiring sufficient sensor sensitivity to accurately capture these variations.
빠른 응답 특성
Sensor response times under 1 millisecond enable real-time tracking of rapid patient respiratory cycle changes. This rapid response capability ensures ventilators can promptly adjust output parameters, preventing patient discomfort or reduced treatment effectiveness due to delays.
장기 안정성 보증
Medical equipment typically requires continuous operation for thousands of hours. WF200DP sensors undergo extensive long-term stability testing, with zero-point drift and full-scale drift controlled within minimal ranges, ensuring consistent measurement accuracy during extended use periods.
3. Ventilator System Integration and Control
